Justin Bieber uses racial slur again, talks KKK in old video

The Miami Beach Police Department has released several booking photos from the Jan. 23 arrest of Justin Bieber. The pop star has pleaded not guilty to charges of resisting arrest, driving under the influence and driving with an expired license.

Justin Bieber seems to have had a proclivity for the N-word in his earlier years, with yet another video of the pop star surfacing that shows him using the racial epithet as a joke.

To add insult to injury, the embattled 20-year-old also mentions joining the Ku Klux Klan, according to the the Sun and TMZ, which obtained the latest clip.

It's the second video to surface in the last week and the latest Bieber blunder to garner negative publicity for the singer. The "Beauty and the Beat" crooner's last year has already included an arrest in Miami, controversy over an egging incident and an attempted robbery case.

Needless to say, tolerance for his antics has sharply dropped off and a petition -- though unsuccessful -- has already attempted to deport the singer to his native Canada.

The first video, released over the weekend, showed the "Baby" crooner using the racial slur as a punch line of a joke. The singer has since apologized for using the "hurtful" language, calling it a "childish" and "inexcusable mistake."

The latest recording shows the YouTube sensation appearing solo in front of the camera as he sings a modified version of his 2009 hit "One Less Lonely Girl." However, instead of saying "Girl," he weaves the epithet into the lyrics, the footage shows.

In the short clip, the grinning Bieber closes the lyric with, "If I kill you, I'll be part of the KKK." Repeated giggles are heard from off-camera.

Bieber is "changing the lyrics of his song One Less Lonely Girl to crack a vile joke about killing black people," the Sun wrote.

"Unfortunately this is the devastating reality of how Justin has behaved and reveals his attitude toward such a deeply emotive subject," a source told the tabloid (via New York Daily News). "People need to see this. Normal kids in society do not make these kind of jokes. He is protected by a network of staff, but the camera doesn't lie. This is the real Justin."

Celebrity mug shots through the years.

As it happens, one of the singer's latest tweet urges followers to "be kind and loving. It is a great way to live."

TMZ reported that Bieber was only doing a parody of a parody, which featured a comedian singing the modified version of the song.

His team told the site that it wanted the video out because Bieber "wants to own what he did."

His mentors, singer Usher Raymond and actor Will Smith, were informed about the recordings, the site said, adding that Bieber knew almost immediately it was a stupid thing to do.

The videos have reportedly been held against the singer for years.

The earlier clip featuring Bieber telling the racist joke at age 15 was reportedly the subject of a million-dollar dispute over confidentiality between the singer's camp and the man who obtained it, TMZ reported Wednesday.
